Jesus told us that it was better for us if He went away. He said this because if He left, the Holy Spirit would come. So it is better for us to have the Holy Spirit in us, then to have Jesus here in the flesh with us and these are some of the reasons why.
He Pray's For Us: So too the [Holy] Spirit comes to our aid and bears us up in our weakness; for we do not know what prayer to offer nor how to offer it worthily as we ought, but the Spirit Himself goes to meet our supplication and pleads in our behalf with unspeakable yearnings and groaning’s too deep for utterance. Romans 8:26

He Teaches Us Everything: But the Comforter (Counselor, Helper, Intercessor, Advocate, Strengthener, Standby), the Holy Spirit, Whom the Father will send in My name [in My place, to represent Me and act on My behalf], He will teach you all things. And He will cause you to recall (will remind you of, bring to your remembrance) everything I have told you. John 14:26
He Gives Us Gift’s: To another [wonder-working] faith by the same [Holy] Spirit, to another the extraordinary powers of healing by the one Spirit; To another the working of miracles, to another prophetic insight (the gift of interpreting the divine will and purpose); to another the ability to discern and distinguish between [the utterances of true] spirits [and false ones], to another various kinds of [unknown] tongues, to another the ability to interpret [such] tongues. 1 Corinthians 12:9-10
He Guides Us: But I say, walk and live [habitually] in the [Holy] Spirit [responsive to and controlled and guided by the Spirit]; then you will certainly not gratify the cravings and desires of the flesh (of human nature without God). Galatians 5:16
He Control Us: Then Peter, [because he was] filled with [and controlled by] the Holy Spirit, said to them, Rulers of the people and members of the council (the Sanhedrin), Acts 4:8
He Cause Us To Live Right: And I will put my Spirit within you and cause you to walk in My statutes, and you shall heed My ordinances and do them. Ezekiel 36:27
He Gives Us Courage: And when they had prayed, the place in which they were assembled was shaken; and they were all filled with the Holy Spirit, and they continued to speak the Word of God with freedom and boldness and courage. Acts 4:31
He Protects Us: And do not grieve the Holy Spirit of God [do not offend or vex or sadden Him], by Whom you were sealed (marked, branded as God’s own, secured) for the day of redemption (of final deliverance through Christ from evil and the consequences of sin). Ephesians 4:30
Most of us tend to believe that we have to do all of these things on our own. But our Freedom through Christ is that He has given us our Father’s Holy Spirit and He does all of these things for us. Jesus has given us the very power that insures that we will never fail. Through the power of our Father we are always victorious and none of us will be lost or fall short of our calling. If we could, then that would mean that Holy Spirit had fallen short, and He just doesn’t fall short! We now have what Jesus said was so important to have and He is responsible to carry out all of these things in our lives.
